Leone” E
Note:
it should be noted that precedence is to the higher note if two more keys are
pressed simultaneously. This assures tonal clarify.

The Tone Levers
(full effect)
ey
Preset Tones
To the left of the upper and lower manuals are series of
tone levers which control the Electone voices that will
sound when the keys are depressed. They are divided
into groups for upper, lower and pedals, so that different
registrations can be set for each.
Upper Manual Levers 9 voices
Lower Manual Levers 5 voices
Pedal Levers 2 voices
Each lever provides two methods of control. One is by
continuously moving the lever from off to full, to achieve
the exact setting for that tone, and thus balancing the
overall tone setting with perfect precision. Each lever also
has two easy-to-feel click stops, at 1/3 and 2/3 positions.
This lets you refind any setting with mathematical pre-
cision and no guesswork in a matter of seconds,
PITCHES OR FOOTAGES
The BK-20C has four different pitch levels, indicated by
the numbers 16’, 8’, 4° and 233". These are standard musi-
cal abbreviations showing the tone’s pitch in relation to
the fundamental (written note). An 8’ tone will sound just
as it has been written. As the numbers increase, the tones
lower. A 16’ tone will provide a tone exactly one octave
lower than the written note.
Similarly, 4° tones are one octave higher than the written
note, 27s tones are one octave and a fifth higher than the
8' fundamental.
To the left of the lower manual are eight Upper Preset
Tone selectors (seven tones plus Cancel). These on/off
switches are special tonal blends that most closely re-
semble the instruments they name (Accordion, Piano,
Hawaiian Guitar, Banjo) as well as three special preset
combinations.
Since these buttons are factory preset, they automatically
cancel all other upper manual tone lever settings. This
lets you switch back and forth. In addition, precedence is
to the right. This means that if two or more buttons are
pressed, the one to the right will take effect. To switch
from one button to another it is not necessary to first
press the cancel button.
Note: Upper Sustain control lever does not work with the Accor-
dion, Piano, Hawaiian Guitar and Banjo preset selectors.
ORGAN PRESET ENSEMBLE
This lever controls the effect which adds the upper tone
lever to the upper preset tone. (Accordion, Piano, Hawaiian
Guitar, Banjo)

&
Vibrato, Vibrato Speed
Vibrato is a waving of the tone. You will see violin and cello players use it freely by an oscillating
motion of the left hand. That increases the emotional quality of the violin tone. This vibrato lever
produces the same vibrato effect. The Vibrato lever provides continuous adjustment of this effect’s
depth, while Vibrato Speed lets you continuously set the desired speed.
Brilliance
With this single, continuously-variable control you can pinpoint the degree of overall softness or clarity
desired for any mood of music.
Upper 8’ 4’ Sustain
When this is switched on, the sustain effect is evoked. As the name of the tab implies, only 8’ and 4’
tones are affected. The length of such sustain is set by the Upper Sustain control.
Note: When combined with Upper Percussive 4’, all sound is canceiled.
Reverb
The reverberation effect, which makes your playing sound full and rich as if you were playing in a large
hall, can be adjusted continuously and smoothly to suit your taste.
Upper Percussive
Changing the beginning of some or all notes can do wonders for lively selections. Your BK-20C’s per-
cussive effects provide subtle but important shading at the moment each note is heard. The special
popping 4’, 2%’ percussive drive can be smoothly blended into all upper manual tones with percussive
4’, 2%", and a percussive length lever regulates the length of decay for this effect.
With percussive, use a detached fingering. Each note should be played cleanly; slurred notes will
diminish the percussive impact.
Note: If Upper Percussive 4’ is set at the same time as Upper Sustain, no sound will be heard.
Percussion (LOWER BRUSH, PEDAL CYMBAL)
Provide lively brush (hissing snare drum brush) and cymbal percussion sounds with each lower manual
or pedal note.
Attack Wah-Wah
Provides a spicy wah-wah sound at the beginning of every upper manual tone.
Repeat Speed
Cuts and repeats each note just like the double-strumming effect of a mandolin. The lever provides
continuous speed adjustment to create a full variety of different moods. Affect upper manual notes
only.
Glide
While the foot switch is pushed when the Glide selector is on, tones will be lowered one half tone.
Pedal Sustain
This control provides continuous adjustment of the sustain effect on the pedals and allows the pedal note
to continue to sound a few seconds after you have released it.

kO)
Tremolo/Chorus
The Electone’s special tremolo is produced by a rotary
[ae speaker that actually spins just behind the rotary speaker
SLOW, grille on the side of the cabinet.
The tremolo selector is complemented by a continuous
tremolo speed control knob.
When the speed control is set to its maximum position,
TREMOLO SPEED the Tremolo will turn the speaker at normal revolution.
The Chorus will turn it at one revolution. Once either
tablet is switched on, it takes several seconds for the rotary
speaker to attain the standard speed. This is also true
when switching to a slower speed (Tremolo to Chorus),
TREMOLO the speed variation will be heard in the music.
If you wish an instant tremolo or chorus sound, be sure to
siwtch on that tablet well in advance of the speaker selec-
jaune tor. For special selections you can use this speed variation
by switching the speaker on first, the Tremolo or Chorus
switch later.
Note: Only Tremolo is produced when Tremolo and Chorus are
CHORUS switched on simultaneously .
UPPER VOICE
Lets you divert upper manual voices from the main to the
rotary speaker.
LOWER VOICE
Does the same for lower manual voices.
FLUTE
SPLIT
FLUTE
SPLIT
This tablet feeds Flute voices of the upper and lower
- manuals and preset Combinations to the rotary speaker.
TREMOLO
Combined with other manual voices through the main
speaker it creates a rich, singing blend.
Note: Only Flute Split is produced when Flute Split and Upper or
Lower Voices are switched on simultaneously.
Manual Balance
This control governs the volume strength of the upper and lower manuals. It is normally left in the
center position, but can be shifted to stress the melody or accompaniment in a selection or passage.
This control can also be used to compensate for a higher number of total tone lever settings (which
would ordinarily result in higher volume) on one of the two manuals.
Expression Pedal
Affect the emotional mood of every passage by letting you vary the volume continuously with your right
foot. This works within the range set by the master volume control.
Master Volume
This is determines the maximum volume obtainable by depressing the expression pedal.

“@)
Auto Rhythm Section
This section provides eight catchy rhythms, each one pro-
duced by a simple button. You can also create more
rhythm variations with the variation button. In addition
to a combined volume and balance knob, tempo control
and tempo indicator light, there are two other switches:
ordinary Start and the Yamaha Synchro-Start which begins
the rhythm accompaniment on the first beat of a measure,
when the first lower manual or pedal note is struck. The
special expression pedal foot switch lets you stop and
restart the rhythm at any point during play.
NORMAL START
For instant rhythm at the beginning of a selection, push
the rhythm selector desired, then flick the Start switch on.
SYNCHRO-START
Select the rhythm, switch on the Synchro-Start and begin
to play once you have the beat established. The rhythm
will begin as soon as you strike a lower manual or pedal
note. This switch permits you to lead in with a rhythm-
free melody at first if so desired.
You can switch off the Auto Rhythm with the foot
switch. When you wish to continue hearing the Auto
Rhythm, be sure to switch on with the foot switch.

RHYTHM FOOT SWITCH
This tab activates a click-switch located at the left side of
the expression pedal. When the tab is on and the rhythm
section operating, touch the foot switch once and the
rhythm automatically stops. Touch it again to switch back
on.
Note: The tab controls the foot switch. If the rhythm has been
cut by the switch and one of the rhythm start switches is
stili on, cancelling the tab will erase the effect of the foot
switch - - in other words, the rhythm will go back on again.
TEMPO
The tempo of the Auto Rhythm section can be adjusted
by a continuous control knob. This is best accomplished
by turning on the Synchro-Start switch.
Although no sound will be produced, the indicator lamp
will flash each quarter note, letting you visually check the
tempo while you adjust.
VOLUME
Use it to balance the volume of the rhythm section and
the manuals. This volume is then varied during the selec-
tion by the expression pedal, just like that of the other
tones.
BALANCE
This control lets you balance the low rhythm sounds, such
as drums, and the high sounds (i.e., cymbals) according to
your mood and the selection. It can make a big difference
even when using the same rhythm. Turn the knob to the
right to accentuate the higher (treble) sounds, to the left
for lower (bass). If you accentuate the treble sounds the
rhythm becomes brighter.
Check the playing hints for specific settings.

Auto Bass/Chord Fun Blocks
NORMAL SINGEL FINGERED CON- MEMORY
FINGER CHORD STANT
CHORD
C chord
The BK-20C is equipped with a “Fun Block” section of
five buttons which can be used in conjunction with the
Auto Rhythm section (see p. 7). It enables you to play
a variety of alternating bass chord rhythms, with the pedal
and chords automatically matching the melody notes,
simply by holding down either a single lower manual key
or a lower manual chord, according to which fun block
button you press. From your very first keyboard attempt,
the fun block feature will let you sound like a pro, making
full rhythmic use of the lower manual and pedals. Here
is how it works.
Note: When the Auto Bass/Chord section is used, the tone color of
the lower manual voices will change from Horn 8’ to Piano,
from Cello 8’ to Guitar, and from Cello 4’ to Harpsichord.
SINGLE FINGER CHORD (THE EASY PLAY WAY)
è Set the tone levers for the tones you want on the lower
manual both Piano and Guitar sounds are available); use
either or both levers to adjust the Auto Bass Chord
tone color and volume in the normal way.
è Match the setting of the Pedal tone lever to the lower
manual tones.
è Select a rhythm pattern and push the corresponding
button until it clicks and stays down.
è Set the Rhythm Start switch on.
e Adjust the rhythm tempo and volume.
e Press the Single Finger Chord button.
Now, if you press a C key on the lower manual, a C major
chord will play in an alternating pattern which matches the
rhythm pattern and tempo set.
As long as the key is held down, the bass chord rhythm
continues, When the Black-key pedal is pressed, the chord
changed from major to minor, and when released, the
chord returns to major. When the White-key pedal is
pressed, the chord changes from major to seventh, and
when released, the chord returns to major. When both
Black- and White-key pedals are pressed, a minor seventh
results.
Note: The bass note will play the root and fifth of any chord
pressed, except when the Jazz Rock rhythm is used; in that
case the bass sounds the root only.

Bass Variation
1-5 1-3-5 1-75
The Electone BK-20C lets you choose one of three bass
patterns to match the lower manual harmony.
When the Single Finger Chord button is depressed, the
three bass variations are created, just as when the Fingered
Chord button is depressed.
Note: This bass variation works with Rhumba and Slow Rock
beats. If the Rhythm Variation button is pressed, however,
then bass variation will be available with Rhumba only.
D
1-5
This is the basic pattern; it alternates the root (1) and fifth
(5) in the bass regardless of rhythm chosen or type of
chord. The one exception is the Jazz Rock rhythm, which
maintains root (1) pedal and no alternation.
Note: The Slow Rock and Jazz Rock rhythms play only the root
{1), when the Rhythm Variation is switched on.
2
1.3.5
This selector effects the Slow Rock and Rhumba rhythms,
with which it will play a root (1), third (3), and fifth (5)
pattern. All other rhythms function as with the (1.5)
selector.
Note: The Rhumba rhythm will play a root (1), third (3), and fifth
(5) pattern, when the Rhythm Variation is switched on.
1:7-5
This selector effects the Siow Rock and Rhumba rhythms
when a seventh or minor seventh chord is being played,
with which you will hear the root (1), seventh (7), and
fifth (5) bass notes. When playing a major or minor
chord the unit will perform exactly as it does with the
second Bass Variation selector (1-3-5).
Note: The Rhumba rhythm will play a root (1), seventh (7), and
fifth (5) pattern, when the Rhythm Variation is switched on.

If there is a powerful transmitter such as a radio station
in the vicinity this can occur. Contact your Yamaha
dealer.
By ices pedal notes sound too high, upper keyboard’s notes
too low. This is especially noticeable when comparing
the Electone with piano. Piano tones are combinations of
harmonics and must interact with their surroundings,
while Electone harmonics are simpler (multiples of the
fundamental tone), requiring the Electone to be adjusted
differently at the assembly stages.
Ge. cis rattling (sympathetic vibration) occurs.
AIl materials have critical resonance frequencies at
which they vibrate. The Electone’s continuous tones
will naturally cause other objects (windows, shelves, etc.)
to vibrate.
